it does not work

this is my string: \u092A\u094B\u0937\u093E\u0939\u093E\u0930

string unicodeString = HttpUtility.HtmlEncode("\u092A\u094B\u0937\u093E\u0939\u093E\u0930");
                 MessageBox.Show(unicodeString);

string unicodeString = HttpUtility.HtmlEncode(above_code);
                 MessageBox.Show(unicodeString);

the string takes value in this form: "\\u092A\\u094B\\u0937\\u093E\\u0939\\u093E\\u0930";

static string DecodeUnicode(string s) {
    StringBuilder sb=new StringBuilder();
    while (s.Length!=0) {
        sb.Append((char)int.Parse(s.Substring(2, 4), NumberStyles.HexNumber));
        s=s.Substring(6);
    }
    return sb.ToString();
}

string s="\\u092A\\u094B\\u0937\\u093E\\u0939\\u093E\\u0930";
log(s);
s=DecodeUnicode(s);
log(s);
